Chicken fat can also be turned into biodiesel

Thread Content

Researchers at Arkansas State University in the United States have recently announced that chicken fat can be converted into biodiesel fuel using a supercritical methanol method. This discovery will make alternative fuels more abundant and accessible, and it will significantly reduce the costs of raw materials and other agricultural by-products. 　　When a substance is heated and pressurized to its critical point, it enters a \"supercritical\" state; the extremely high temperature and pressure allow the substance to exist in a balanced state between gas and liquid phases. Using this theory, researchers carried out chemical reactions between low-grade chicken fat and tall oil fatty acids using the supercritical methanol method. Under high temperature and pressure, the supercritical methanol method is used to dissolve chicken fat and tall oil fatty acids, and reactions occur between their components, thereby producing a biooil derived from chicken fat. 　　Producing biodiesel from animal and vegetable oils has always been a project that countries strive to develop. Biodiesel can be used as a biofuel as well as an additive for diesel engine fuel. Currently, Europe and North America primarily use vegetable oils as raw materials to produce biodiesel, while Japan produces biodiesel by recycling used cooking oil. 　　Researchers say that the new findings will prompt energy-producing countries to reconsider the value of oil and biodiesel, and major oil companies have begun to focus their research efforts on using biodiesel as a substitute for petroleum fuels. Producing crude oil and raw materials from chicken fat is obviously much cheaper and more environmentally friendly.
